Abstract
The invention discloses a set-top-box type high-definition conference terminal which comprises a high-definition video capture card and a coding-decoding chip, wherein the coding-decoding chip is connected to the high-definition video capture card. The set-top-box type high-definition conference terminal further comprises an MCU which is provided with a plurality of serial interfaces, wherein the MCU further comprises a bus transceiver and an information processor. The bus transceiver is respectively connected with the coding-decoding chip and the information processor, and the serial interfaces are respectively connected with the information processor. The set-top-box type high-definition conference terminal provided with the MCU which is provided with the serial interfaces is used for connecting terminal equipment of each branch video conference place, namely, the set-top-box type high-definition conference terminal achieves the objective that one set-top-box type high-definition conference terminal is connected with a plurality of network nodes simultaneously. Therefore, the set-top-box type high-definition conference terminal is beneficial to reducing the complexity of a multi-point conference set networking structure, reduces the number of the set-top-box type high-definition conference terminals, and facilitates management and maintenance of the set-top-box type high-definition conference terminal.
Description
Technical field
The present invention relates to communicate to connect circuit field between modulator-demodulator and the computer, particularly relate to a kind of set-top box type high definition conference terminal.
Background technology
Along with the development of network technology, network technology successfully applies to video conference.The multipoint control unit of video conference (MCU) is the nucleus equipment of video conferencing system, the terminal of all conference participations can be set up man-to-man the connection with MCU, the HOST terminal is responsible for gathering sound and the image in meeting-place, place, then be transferred to MCU after encoded, according to the mode decision of current video meeting processing mode and the forwarding logic to audio-video signal, the audio, video data after will processing at last re-sends to each participant by MCU.MCU in the centralized multipoint videoconference integrates multipoint videoconference controller (MC) and multipoint videoconference processor (MP), the function of its existing organization and management meeting is responsible for all participants' sound and processing and the switching of image simultaneously.
The existing special-purpose terminal equipment that is used for video conference comprises meeting room type, desktop type and set-top box type three classes, and set-top box type video conference terminal is different from front two kinds, it is not integrated on open PC platform, equipment itself does not have CD-ROM drive, floppy drive, operating system has the characteristics of high stability, has obtained using widely.Yet when existing a plurality of meetings field point carried out multipoint conference, a plurality of network nodes place often needed a plurality of MCU terminal equipments to carry out simultaneously mutual communication to finish a plurality of meeting field points, thereby caused MCU terminal equipment complicated layout, override to safeguard the shortcomings such as inconvenience.
Summary of the invention
When carrying out multipoint conference for above-mentioned existing a plurality of meetings field point, a plurality of network nodes place often needs a plurality of MCU terminal equipments to carry out simultaneously mutual communication to finish a plurality of meeting field points, thereby cause MCU terminal equipment complicated layout, override to safeguard the problem of the shortcomings such as inconvenience, the invention provides a kind of set-top box type high definition conference terminal.
For achieving the above object, set-top box type high definition conference terminal provided by the invention solves problem by following technical essential: set-top box type high definition conference terminal, comprise high definition video collecting card, codec chip, described codec chip is connected on the high definition video collecting card, also comprise the MCU with a plurality of serial line interfaces, described MCU also comprises bus transceiver and message handler, described bus transceiver links to each other with message handler with codec chip respectively, and described a plurality of serial line interfaces link to each other with message handler respectively.
MCU with a plurality of serial line interfaces is used for connecting the terminal equipment of each branch's video conference place, MCU utilizes built-in message handler to encode after receiving each sub-venue signal, sent into by bus transceiver again and descend the coded program of encoding according to certain form together in the codec chip, information flow behind the coding enters the high definition video collecting card at last, finally finishes the collection of each sub-venue high definition video and acoustic information stream and compiles work; Set-top box type high definition conference terminal is carried out above-mentioned opposite operation to the information data that each sub-venue sends.
Preferably, described a plurality of serial line interface is RS-232 interface.RS-232 interface is the communication interface of computer standard configuration, is convenient to the terminal equipment of MCU and each branch's video conference place, and simultaneously, RS-232 interface can be checked by hyper terminal the data of serial ports, and PC easy to use detects analysis to circuit.
Preferably, described high definition video collecting card is the HDMI capture card.The HDMI capture card is supported on the single line cable and transmits, without digital high definition, multichannel audio and the intelligent format of compression and the digital interface of control command data, simultaneously, the HDMI capture card have high stability, multi-functional, compatible wide, the characteristics such as secondary development bag SDK are provided.
Preferably, described codec chip is TW2880 high definition chip.TW2880 can accept 16 road D1 input and simultaneously playback 16 road D1 simultaneously, and exports simultaneously 16 road D1 to the rear end compression chip, has advantages of that encoding and decoding speed is fast and efficient is high.
Further, described MCU also comprises address decoder, and described address decoder links to each other with bus transceiver.The address compilation device that arranges is intended to after address decoder Input Address control signal, and address decoder provides the address of appointment so that bus transceiver has reading of target and distribute data to bus transceiver.
Preferably, described message handler is 8031 processors.Satisfying under the prerequisite that video data, voice data and simple control signal transmission operational capability are required, embed 8031 mature and stable processors, both can control the cost of MCU, guarantee that simultaneously MCU is stable.
The present invention has following beneficial effect:
Be provided with the set-top box type high definition conference terminal of a plurality of serial line interface MCU, be used for connecting the terminal equipment of each branch's video conference place, realize that single set-top box type high definition conference terminal connects the terminal equipment of each meeting-place video conference simultaneously, realize that namely a set-top box type high definition conference terminal connects a plurality of network nodes, be conducive to reduce the complexity of multipoint conference group network structure, reduce simultaneously the quantity of set-top box type high definition conference terminal, be convenient to administering and maintaining of set-top box type high definition conference terminal.
